By volume, there are about 4 trillion m of peat in the world covering a total of around 2% of global land area (about 3 million km ), containing about 8 billion terajoules of energy. Peat exploitation in East Frisia, GermanyPeat deposits are found in many places around the world, notably in Ireland, Russia, Belarus, Ukraine, Finland, Lithuania, Latvia, Estonia, Scotland, Northern England (Particularly in the Pennines), Wales, Poland, northern Germany, the Netherlands, Denmark, Norway, Sweden, New Zealand and in North America, principally in Canada, Michigan, Minnesota, the Florida Everglades, and California's Sacramento-San Joaquin River Delta.
